8. S/PDIF Connector
S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides
impressive audio quality through optical fiber and allows you to enjoy digital audio instead of analog
audio. Through a specific audio cable, you can connect the S/PDIF connector to other end of the
S/PDIF audio module, which bears S/PDIF digital output. Normally there are two S/PDIF outputs as
shown, one for RCA connector, the most common one used for consumer audio products, and the
other for optical connector with better audio quality. Same as outputs, you can also connect RCA or
optical audio products to input connectors on the module and have the voice or music come out from
your computer. However, you must have a S/PDIF supported speaker/amplifier/decoder with S/PDIF
digital input/output to connect to the S/PDIF digital input/output to make the most out of this function.
This motherboard comes with an ALC650F CODEC, which supports high quality of 5.1
Channel audio effects, bringing you a brand new audio experience. On the strength of the
innovative design of ALC650F, you're able to use standard line-jacks for surround audio
output without connecting any external module. To apply this function, you have to install the
audio driver in the Bonus Pack CD as well as an audio application supporting 5.1 Channel.
Picture bellow represents the standard location of all speakers in 5.1Channel sound track.
Please connect the plug of your front speakers to the green “Speaker out” port, rear
speakers’ plug to the blue “Line in” port and both of the center and subwoofer speakers to
the red “MIC in” port.

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if
you are not an over-clocker, we recommend you to set it to the default setting. Additionally,
this motherboard also provides “
1MHz Stepping Adjustment
” feature for overclockers to
adjust CPU FSB frequency via BIOS setup program. If you fix the CPU FSB frequency by
JP21, the “1MHz Stepping Adjustment” range will be changed according to what type of
CPU you use.
